I'm having a very strange problem. All my USB ports were working fine until today. I was at school at the time of the failure, but I got home to find the mouse not working. I initially thought it was the mouse and its wires coming loose or something (so I took it apart and now I can't get it back together; good for me...), but then I noted that all other USB devices malfunction in the same exact way. What happens is the device is recognized/powered for a split second only. The mouse provides the best example: Plug it in while watching the laser, and as you slide the plug in, you'll see the laser flash on then instantly off. Same with the power light on my headset. My MP3 player also behaves similarly, though it's harder to see because of the way the screen loads when connecting to a computer.
My ma reports that the mouse was working fine this morning, and she didn't restart the computer at all. The computer was not asleep when I found it, just unresponsive to mouse input. I initially thought it was a different problem we've been having with the system hanging. I will explain that as well in case it has any bearing on this one: Basically, every so often, the system just freezes to all input, and these lines start flickering across the screen - king of like the lines in an old film that used to flash around. They're just very thin, fuzzy lines, almost like mild static. At that point, the system must be rebooted. Often, on the re-start, the BIOS appears stating that "DQS training" failed on previous boot, and it has reverted to a slower DRAM speed. It says to press F2 to continue, which I do, after which it does some sort of operation, then kicks me to the BIOS control menu. Every time, I've just hit "save changed and exit," but that, not surprisingly, hasn't solved the problem.
A little time on Google told me that "DQS training" is something to do with overclocking, so you should know that I don't do any such thing with this machine.
We quite need the USB. Without it, we have no headset and no printer, which is not good. Anyone who can help with the crashes would also be appreciated, because we have lots of important documents on this machine, and it would not be good to lose them. Final question: If Windows crashes (not as in a bluescreen/restart situation, but a situation where Windows is ruined and cannot boot), can you pull the hard-drive from the machine and offload files if you plug it into another computer, or does losing Windows ruin every file on the drive? I don't see why it should, but with computers, the impossible becomes possible sometimes...
Last detail: The USB mouse did seem to flash a bit if I jiggled the wire (on the mouse's end), at first, but it didn't do that when I tried again later, and it's not doing anything right now with my headset. Please help if you can!
